Viola plant named ‘Bonny’

ABSTRACT

A new cultivar of  Viola  plant named ‘Bonny’ that is distinguishable by compact basally branching habit, medium to large single bicolored blooms consisting of two lavender-colored upper petals and two bright yellow lateral petals and one bright yellow lower petal, and flowers which are heavily pleasantly fragrant. ‘Bonny’ is hardy in USDA Zone 5 and blooms from early spring through fall.

Genus and species: Viola×hybrida.

Variety denomination: ‘Bonny’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of Viola,botanically known as Viola×hybrida and hereinafter referred to by thevariety name ‘Bonny’. ‘Bonny’ originated and was selected from a largepopulation of hybrid seedlings from an open-pollinated Viola breedingprogram which was started by the inventor in 2010. The breeding programwas conducted in a greenhouse nursery in Lincoln, Lincolnshire, UnitedKingdom. The aims of the breeding program were to produce a series ofnew Viola varieties exhibiting a range of flower colors borne onvigorous plants which are highly scented.

In spring 2011, the inventor organized open-pollination usingcombinations of selected, unnamed and unreleased seedlings retained fromprevious breeding cycles. The male and female parents of ‘Bonny’ areunknown. Seeds were harvested in late summer 2011, sown and grown overwinter as seedlings which flowered in spring 2012. ‘Bonny’ was selectedby the inventor in spring 2012. The inventor selected ‘Bonny’ togetherwith the inventor'co-pending varieties ‘Amy’ (U.S. Plant Ser. No.14/998,506), ‘Sunny Jim’ (U.S. Plant Ser. No. 14/998,507), and‘Sweetheart’ (U.S. Plant Ser. No. 14/998,505) for their close similarityin plant habit and flower size and in order to create a consistent anduniform series.

‘Bonny’ was first vegetatively propagated by the inventor in spring 2012using asexual shoot cuttings. ‘Bonny’ has been found to reproduce trueto type in successive generations of asexual propagation.

SUMMARY

The following traits have been repeatedly observed and represent thedistinguishing characteristics of the new Viola cultivar named ‘Bonny’.‘Bonny’ has not been tested under all possible conditions and phenotypicdifferences may be observed with variations in environmental, climatic,and cultural conditions, however, without any variance in genotype.

The following are the most outstanding and distinguishingcharacteristics of this new variety when grown under normalhorticultural practices in Lincoln, Lincolnshire, United Kingdom.

-   -   1. ‘Bonny’ exhibits a naturally basally self-branching plant        habit.    -   2. The foliage mound of ‘Bonny’ is 10 cm in height and 15 cm in        diameter in its first season of flowering.    -   3. ‘Bonny’ exhibits medium to large single, bi-colored blooms        consisting of two lavender-colored upper petals and two bright        yellow lateral petals and one bright yellow lower petal.    -   4. The flowers of ‘Bonny’ are 3.8 cm in diameter.    -   5. ‘Bonny’ blooms are heavily pleasantly fragrant.    -   6. ‘Bonny’ does not require vernalization to initiate flowers.    -   7. ‘Bonny’ blooms continually from spring until fall.    -   8. ‘Bonny’ is hardy to USDA Zone 5.

DESCRIPTION OF THE PHOTOGRAPHS

The new Viola plant ‘Bonny’ is illustrated by the accompanyingphotographs which show each plant's overall plant habit including form,foliage, and flowers. The photographs are of plants 10 weeks in agegrown in outdoor conditions. The colors shown are as true as can bereasonably obtained by conventional photographic procedures. Bothphotographs were made from a plant which has been grown outdoors inOxnard, Calif. No pinching or chemical growth regulators have beenemployed. The photographs were made using conventional techniques andalthough flower and foliage color may appear different from actual colordue to light reflectance, they are as accurate as possible byconventional photography.

DESCRIPTION OF THE NEW VARIETY

The following is a detailed botanical description of the new Violacultivar named ‘Bonny’. Observations and measurements were collected inSeptember 2015 from 12-week-old plants which were growing in 1-galloncontainers out of doors in Oxnard, Calif. Color determinations were madein accordance with the 2007 edition of The Royal Horticultural SocietyColour Chart from London, England, except where general color terms ofordinary dictionary significance are used.

COMPARISON TO COMMERCIAL VARIETY

The inventor is not aware of any variety of Viola, whether produced fromcuttings or from seed, which exhibits similar bi-colored flowers. Inaddition, the inventor selected ‘Bonny’ for the absence of prominentlower petal veining which is typical of many Viola varieties.

I claim:
 1. A new and distinct cultivar of Viola plant named ‘Bonny’ asdescribed and illustrated herein.
